Key Features
Key Features
• High-SPL, high-efficiency system for the
sound reinforcement and PA markets.
• BroadBeamHP
®
wide dispersion pattern
provides smooth off-axis coverage and
reduces overall system costs.
• One 203 mm (8.0 in) concentric coaxial
coated fiber driver, 25 mm (1.0 in) com pression driver with a 50 mm (2.0 in)
titanium diaphragm.
• Voice coil/8 Ohm direct & 70.7/100 Volt
model options.
• Includes tile bridge, safety cable
and backcan for ease of ordering
and installation.
• Low-profile design for clean appearance.
• Dual-concentric driver design provides
uniform horizontal coverage.
• Black & white color options.
Applications
Applications
The HPCF8 is a high-SPL flush-mount
speaker with BroadBeamHP
®
dispersion
technology providing a wide coverage pattern for in-ceiling applications. The HPCF8
is engineered for installations requiring
full-range background and foreground
music plus paging. A smooth and even
coverage pattern makes the HPCF8 an
ideal choice for use in gyms, aerobic rooms,
convention centers, stadiums and other
high-power in-ceiling applications.
BaBackcan
ckcan
HPCF8 in-ceiling speakers are packaged
with grille, tile bridges and backcan. HPCF8
backcan is UL listed for plenum spaces and
houses the electrical sub-assembly and all
connection hardware.
Crosso

ver Network
ver Network
An advanced crossover network with
low-phase shift and impedance equalization generates a coherent wave front. The
HPCF8 crossover incorporates UL-listed,
military grade glass-epoxy board material
for long-term reliability.

itectural Specifications
itectural Specifications
The loudspeaker shall be of in-ceiling
design consisting of one 203 mm (8.0 in) concentric coaxial coated fiber driver,
25 mm (1.0 in) compression driver with a
50 mm (2.0 in) titanium diaphragm. The
low frequency voice coil diameter shall be
50 mm (2.0 in).
Performance specifications of a typical
production unit shall be as follows: Usable
frequency response shall extend from
52 Hz – 17.3 kHz. The loudspeaker shall be
available in separate 64 W transformer and
8 Ohm models. Taps shall be nominally
4 W @ 70.7 V (8 W @ 100 V), 8 W @ 70.7 V
(16 W @ 100 V), 16 W @ 70.7 V (32 W @ 100
V), 32 W @ 70.7 V (64 W @ 100 V), 64 W @
70.7 V (tap position not used @ 100 V). The
frequency-dividing network shall have
a crossover frequency of 1.8 kHz. Rated
power capacity of the components and
network shall be at least 125 Watts continuous RMS power.
The HPCF8 backcan shall be constructed of formed steel and the baffle of
heat-resistant ABS material. The external
wiring shall be accomplished via hardwire
leads.
The system shall include a steel support
backing plate (tile bridge) to reinforce the
ceiling material and tile support rails. The
